Hasse diagrams of basic blocks containing four comparable reducible elements and having nullity four

In $2020$, Bhavale and Waphare introduced the concepts of fundamental basic block and basic block, associated to dismantlable lattices. Further, they have provided the recursive formulae of the number of non-isomorphic fundamental basic blocks as well as basic blocks, containing $r$ comparable reducible elements and having nullity $l$. In this paper, we actually obtain the Hasse diagrams of the basic blocks containing four comparable reducible elements and having nullity four.
